(1) REGULATORY FRAMEWORK: GDPR Art. 5(1)(e) (storage limitation principle) requires data be kept no longer than necessary for the stated purpose. Indefinite retention of conversational data until user action raises questions about compliance with this principle, particularly as the ongoing purpose for retaining old conversations (beyond active service provision) must be justified. French CNIL's 2024 AI data guidance emphasises proportionate retention periods. (2)
